Other Events ------------ ACC Hearing Officer Recommends Changes to ACC Rules and - ------------------------------------------------------- Stranded Cost Orders - -------------------- On February 5, 1999, the Hearing Division of the Arizona Corporation Commission (ACC) issued Proposed Orders regarding Stranded Cost Recovery and Competition Rules for Affected Utilities. TEP must file exceptions to these Proposed Orders by February 17, 1999. Stranded Cost Recovery - ---------------------- As previously reported, on June 22, 1998, the ACC adopted an order which outlined two options for stranded cost recovery: (i) Divestiture/Auction of all generation assets to determine the amount of stranded costs for 100 percent recovery, or (ii) a Transition Revenues Methodology, where the Affected Utility would retain generation assets in a separate affiliate with sufficient revenues necessary to maintain financial integrity, such as avoiding default under currently existing financial instruments for a period of ten years. On February 5, 1999, the ACC Hearing Officer issued a Proposed Opinion and Order (Proposed Order) which recommends modification of the June order so that divestiture is not required for 100% stranded cost recovery. The recommended order allows each Affected Utility to choose from the following four options: 1) Net Revenues Lost Methodology -- Stranded costs would be determined by comparing generation revenues with competition versus revenues without competition. Stranded costs would be separated between regulatory and generation assets. Generation related stranded costs would be recovered over a five-year period as follows: (i) standard offer customers would pay 100% of their proportionate share of stranded costs, and (ii) customers electing to purchase energy from competitors would pay through a competitive transition charge (CTC) on a declining percentage basis, paying 100% in year one, 80% in year two, and decreasing 20% each year. Regulatory assets would be recovered 100% from all customers. Any return on unamortized regulatory assets would be reduced by 20% per year over five years following the initial five-year period. 2) Divestiture/Auction Methodology -- Stranded costs would be the difference between the market value from sale of non- essential generation assets and their book value. Each generation asset would include its portion of appropriate regulatory assets. The Affected Utility would be permitted to recover 100% of stranded costs over a ten-year period, with no return on the unamortized balance. All customers would be charged either through the standard offer rate or through a CTC. 3) Financial Integrity Methodology -- The Affected Utility would maintain financial viability, that is, having revenues sufficient to meet minimum financial ratios (similar to the previous "Transition Revenues Methodology"). All customers would pay their share over a ten-year period either through the standard offer rate or through a CTC. 4) Settlement Methodology -- Some combination of Options 1, 2, and/or 3, submitted as a settlement option. Under the Proposed Order, Affected Utilities may amend their previously filed stranded cost implementation plans by March 19, 1999. TEP's original stranded cost recovery plan, filed on August 21, 1998, specified divestiture of generation assets as the preferred method for recovery given the then available options. TEP intends to file exceptions to the Proposed Order. If the Proposed Order on stranded cost recovery is approved, thereby amending the June 1998 stranded cost order, TEP may amend its stranded cost recovery proposal. Retail Electric Competition Rules - --------------------------------- As previously reported, on December 11, 1998 the ACC adopted the amended Retail Electric Competition Rules (Rules). On January 5, 1999, the ACC stayed the Rules pending additional proceedings to resolve a number of issues required to implement competition. On February 5, 1999, the ACC Hearing Officer issued a Proposed Opinion and Order recommending changes to the Rules. These recommendations include: - -- The date to open an Affected Utility's service territory to competition would be set upon the resolution its of Stranded Costs and Unbundled Tariffs by final ACC order. - -- If an Affected Utility's service territory is open prior to January 1, 2001, the existing phase-in schedule is retained, calling for 20 percent of the market to initially have access to competitive generation supply. As part of the 20 percent, each Affected Utility is to reserve an increasing percentage for residential customers according to a set schedule. - -- Competitive Energy Service Provider affiliates of Affected Utilities may not enter another Affected Utility's service territory until its own territory is open to competition. - -- The requirement for energy generated from solar sources was eliminated, citing it as prohibitively expensive and potentially hindering competition in Arizona. - -- Affected Utilities must file tariffs for unbundled noncompetitive services with the ACC by March 19, 1999. TEP intends to file exceptions on the Proposed Order. If the Proposed Order amending the Rules is adopted, it will be forwarded to the Secretary of State to start the amendment process. The Arizona Administrative Procedures Act requires that the Rules be filed with the Secretary of State before they can be amended. We anticipate that the stay of the Rules would probably remain in effect until amendments are adopted. 1998 Earnings for UniSource Energy and TEP - ------------------------------------------ On February 8, 1999, UniSource Energy Corporation (UNS: NYSE) reported consolidated earnings for the year ended December 31, 1998. Net income for 1998 was $28.0 million, or $0.87 per share, compared to $83.6 million, or $2.60 per share, for the same period in 1997. This difference was primarily due to two items recognized in 1997, but not in 1998: (i) prior period net operating loss tax benefits of $43.4 million; (ii) and reversal of a $6.1 million after-tax loss provision upon dissolution of an investment subsidiary. In addition, net losses related to new businesses increased by $2.7 million, and after-tax interest expense increased $6.4 million due to fixed-rate financings which assured future interest payment stability and reduced refinancing risk. UniSource Energy's unregulated affiliates, held under Millennium Energy Holdings, Inc., incurred a net loss in 1998 of $8.1 million, or $0.25 per share. This compares to a 1997 loss of $5.4 million, or $0.17 per share. TEP recorded net income of $41.7 million in 1998, compared with net income of $83.6 million in 1997. Other than the losses incurred by UniSource Energy's unregulated subsidiaries, the same factors that explain the year-to-year change in UniSource Energy's earnings also explain the change in TEP's earnings. In addition to TEP, UniSource Energy's principal subsidiaries include New Energy Ventures, Inc., a provider of electric load aggregation, energy management and advisory services to retail purchasers of electric energy; Advanced Energy Technologies, Inc., a developer of renewable energy and distributed generation technologies; Nations Energy Corp., an independent power developer; Southwest Energy Solutions; and SWPP Investment Co.
